We PROVE Ancient Sunrise hair dyes to be 100% pure henna, indigo, and cassia, without contaminants, chemical dyes, and metallic salts. We send every batch to an independent laboratory to certify that there are no pesticides or adulterants. There are no hidden ingredients or herbs added to Ancient Sunrise powders. Because these are 100% plant products, they cannot lift hair color. Each kit has been designed according to the art and science of henna to produce the best results. Ancient Sunrise products are safe to use over chemically treated hair. The Ancient Sunrise Henna for Hair Warm Black Kit dyes light, medium or gray hair a soft black shade and adds phenomenal shine! Ancient Sunrise Henna for Hair Warm Black Kit is permanent on natural hair, but may fade slightly on chemically damaged hair. This kit provides enough products to cover hair that is a few inches longer than shoulder length. For best results, use Ancient Sunrise Rainwash prior to application.
